摘要:

发展了一种测量皮秒范围内中子非束缚核寿命的新技术。由于富中子氧同位素的独特结构,26 O-> 24 O +n+n的衰变被预测具有可观的寿命。26 O的半衰期为4.5^{+1.1}-1.5}(stat.)+/- 3(系统)PS.这相当于26 O在82%的置信水平下具有有限的寿命,因此,表明可能存在双中子放射性。

英文摘要:

A new technique was developed to measure the lifetimes of neutron unbound nuclei in the picosecond range. The decay of 26O -> 24O+n+n was examined as it had been predicted to have an appreciable lifetime due to the unique structure of the neutron-rich oxygen isotopes. The half-life of 26O was extracted as 4.5^{+1.1}_{-1.5}(stat.) +/- 3 (sys.) ps. This corresponds to 26O having a finite lifetime at an 82% confidence level and, thus, suggests the possibility of two-neutron radioactivity.
